SPECIFICATION forming part-of Letters Patent No. 461,596, dated October20, 1 891.

Application filed March 20, 1891.

To all whom it may concern."

Be it known that I, OOURTLAND SIMS, a citizen of the United States,residing at Los Olivos, in the county of Santa Barbara and State ofCalifornia, have invented a new and useful Cultivator, of which thefollowing isa specification.

My invention relates to improvements in cultivators; and the objects inview are to provide a cultivator of simple construction and adapted forcultivation of orchards and ridding the same of small weeds, grass, &c.

A further object of the invention is to so construct the apparatus as tocultivate close I 5 to the trees and between the same, as planted inrows, and thereby avoid the loss of time and labor usually expended incross-cultivating and hoeing.

Other objects and advantages of the invention will appear in thefollowing description,

and the novel features thereof will be particularly pointed out in theclaims.

Referring to the drawings, Figure 1- is a perspective of a cultivatorconstructed in accordanee with my invention. Fig. 2 is a transversesection looking toward the rear. Fig. 3 is a detail in perspective ofthe cultivating-blade, its standards, and the adjacent parts, togetherwith the mechanism for ad- 0 justing said blade.

Like numerals of reference indicate like parts in all the figures of thedrawings.

In practice I employ a main central draftbeam 1, near the front of whichthe same is provided with a doubletree 2 and singletrees 3 of the usualconstruction. From apoint in rear of the doubletree there is secured toand diverges from the beam, at one side thereof, a diagonal beam 4, therear end of which is con- 0 nected to the rear end of the beam 1 by arear transverse beam 5, which is extended some distance beyond the beam1, as shown. The beams 1 and 4 are provided with axle boxes or bearings(3, in which is mounted an axle 7, the same extending beyond the beamsand at one end terminating about flush with the beam 5. Ground-wheels 8are mounted upon outside of the beams.

:of the beam 5;

The two beams 1 and 4 are connected in rear of the axle by a seat-bar10, havingaseries of'perforations 11.

The bar is embraced at its rear edge by the lower bifurcated end of arearwardly-disposed inclined seat-standard 12, and through thebifurcations and the bar 10 is passed an adjusting-bolt 13. The

upper end of the seat-standard carries the usual seat 14 for the driver.

In bearing-eyes 15, extending from the rear face of the beam 5, there ismounted a rockshaft 16, provided at intervals with rock-arms 17,connected at their free ends by a longitudinal connecting-bar 18. Therock-shaft and bar 18 are of about equal length,'and the former hasoneend squared, as at 19, to receive the lower end of a bell-crank lever20, the lower branch of which is loosely .connected, as at 21, to theend of the rod 18. A locking-pawl 22 is secured to the lever 20 and isoperated by a small bell-crank 23, located at the upper end ofthe lever20, which latter terminates in a suitable handle, as shown. A toothedlocking-sector is mounted on he beam 5, and the pawl 22 engages with theteeth of the same, so that the lever 20 may be locked at any desiredinclination, and by means of said lever being fulcrumed upon therock-shaft16 the latter may be turned or partially rotated and the rod18 elevated or depressed.

25 designates a pair of standards, which terminate at their upper endsin heads having elongated slots 26, which loosely receive the rod 18,and upon which rod the standards are adapted to slide longitudinally.Near the lower end the standards 25 are provided withforwardly-diverging branches 27,which terminate in eyes 28, that looselyreceive the axle 7, and upon said axle the branches move longitudinallywhen the standards move upon the rod 18. At their lower ends the stand-vminates in a point 30, located beyond the end of the axle 7, when thestandards are moved as far as permissible to the right of the machine.The two branches 27 of the standards are connected by a rack-bar 31, andabove the latter, upon a bearing-bracket 32, located at the intersectionof the beams 1 and 5, is a lever 33, terminating at its upper end in ahandle adjacent to the drivers seat, and at its lower end below thebracket in a toothed segmental head 34:, the teeth of the same engagingwith the teeth of the rack-bar 31.

This completes the construction of the cultivator, and the operation ofthe same, although obvions from the above description, may be brieflystated as follows: The cultivator is drawn along between the rows oftrees, and by means of the hand-lever 20 the cultivator-blade is set therequired distance, so as to cultivate deep or shallow, as the case maybe. In order to elevate the blade over roots that may lie close to thesurface or above the same, the lever 20 may be operated. As thecultivator moves from tree to tree the driver manipulates the lever 33by drawing the same toward and away from him. By drawing the levertoward him the cultivator is thrown outwardly, so as to cultivatebetween the trees of a row, and when arriving at a tree the lever isthrown away from the driver, so as to draw the cultivator inwardly, andthus pass around but close to the tree.

From the above it will be seen that by my invention I avoid anyunnecessary labor in cultivating between the trees and close to the sameby means of hoeing by hand or crosscultivating, thoroughly cultivatingthe orchard by one operation.

Having described my invention, what I claim is a 1. In a cultivator ofthe class described, the combination, with the frame-work, a trans versebar supported therein, of cultivatorstandards loosely mounted forlateral movement upon the bar, a cultivator carried by the standards, atransversely-disposed toothrack bar connecting the standards, a leverterminating in a toothed segmental head and adapted to reciprocate saidbar, and standards laterally pivoted to the frame-work and engaging theteeth of the bar, and means for looking the lever in its adjustedposition, substantially as specified.

2. In a cultivator of the class described, the combination, with theframe-work, the axle extended beyond the same, wheels mounted on theaxle outside of the frame-work but adja'cent thereto, and a reartransverse bar, of cultivatorstandards loosely mounted upon the bar andhaving branches forwardly disposed and terminating in eyes looselyengaging the axle, a cultivator-blade connected to the standards, andmeans for laterally reciprocating said standards, branches, and blade,substantially as specified. y H

3. In a cultivator of the class described, the combination, with theframe-work having the extended axle, the rock -shaft having rockarms,and a rod connecting the rock-arms, ot' a bell-crank lever fixed uponthe rock-shaft, having one branch loosely connected with the rod and itsremaining branch terminating in a handle, standards loosely mounted uponand depending from the rod and adapted for lateral and verticalreciprocation, and provided with forwardly-disposed branches terminatingin eyes loosely connected with the axle, acultivator-blade connected tothe standards, a toothed rack-bar transversely disposed and connectingthe branches of the standards,

and a toothed lever pivoted to the framework and engaging the teeth ofthe rack-bar, substantially as specified.

4. In a machine of the class described, the combination, with the maindraft-beam 1, the diverging beam 4, the journal-boxes 6, axle 7,extending beyond the beams, the brace-rod 9, connecting the draft-beam,axle, and a rear beam connecting the draft and diverging beams, of eyesprojecting from the rear beam, the rockshaft jonrnaled in the eyes andprovided with rock-arms, a rod connecting said arm a bell-crank leverfixed upon the shaft and loosely connected with the rod and providedwith a locking-pawl, a toothed sector at one side of the lever forengaging the pawl, a pair of standards terminating in slotted heads,mounted on the rod and having forwardly-disposed branches terminating ineyes loosely engaging the axle at each side of the wheel and beam 1, thecultivator-blade 29, the toothed bar 31, connecting the branches, thebracket 32, and the segmentally-toothed lever 33, pivoted on the bracketand engaging the locking-bar, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
